Comment # 9 on bug 954783 from Jozef Kovac

I tried yesterday glmatrix even multiple(parallel)  4-6 for for couple of
minutes but  nothing happen(windowed and fullscreen) using ALT+TAB, workspace
switching , also test Unigine Heaven, unigine valley  also ok more than hour.

I tried now  glmatrix  5 parallel and system freezy  after 2-3 minutes.
Torchlight II  game system freezy after  15-20 min of gameplay.
DRI_PRIME=1  steam  work fine,  also in Big picture mode but i tested only
once.


i have  compositor set to xrandrd, because openGL  settings  show only black
screen.  Also on Arch wiki  Black screen with GL-based compositors
